IMPROVEMENT IN DEVICES FOR WINDING CLOCKS.

Specification forming part of Letters Patent No. [66,518, dated August10, 1875; application filed April 20, 1875.

To all whom it may concern:

Be it known. that I, EUGENE FARCOT, of Paris, France, have invented anew Improvement in Stand-Clocks; and I do hereby declare the following,when taken in connection with the accompanying drawings and the lettersof reference marked thereon, to be a full, clear, and exact descriptionof the same, and which said drawings constitute-part of thisspecification, and represent, in

Figure 1, front view of a clock embodying my improvement; Fig. 2, sideview of that part of the movement to which the invention speciallyrelates.

This invention relates to an improvement in that class of clocks whichare wound by means of a cord in connection with a spring barrel orWeight; and the invention consists in combinin g with the drivingspring-barrel a second spring-barrel with a cord wound thereon, so thatby pulling upon said cord the said second barrel is turned, and in suchconnection with the drivin g-barrel as to wind the drivin g-sprin g, andat the same time wind the spring in the second barrel, so that when thecord which turns the said second barrel is released, it will be rewoundby the reaction of the spring in the said second barrel.

A is the driving-barrel of a clock-movement, of substantially the usualconstruction and arran gement, for imparting its power to move the handsof a clock-strikin g movement or alarm, or all, as the case may be. Inrear of this barrel, and loosely upon the same line of axis, is a secondand similar barrel, Gr, within which is a spring. Around this secondbarrel G a cord or ribbon, T, is wound, its end extending below theclock and terminating in a tassel,

as shown, or other convenient device, the arrangement of the cord on thebarrel Gr being such that, by pulling down upon the cord, the barrelwill be rotated so as towind the spring within it, and that whenreleased the reaction of the spring will draw up and rewind the cordupon the barrel. On the mainspring shaft E a disk, A, is loosely fitted,and'to this a lever, I, is hung by one end, the other end eX- tcnding upinto a fork, F, projecting forward from the second barrel G, as seen inFig. 2. Fast to the shaft E is a ratchet, D, and on the lever I is apawl which works into the teeth of the said ratchet, so that when thebarrel G is turned by drawing down the cord the lever I will engage theratchet D and cause the winding of the mainspriug, and when the powerwhich draws down the cord is removed and the barrel G returned, thelever I will turn back freely with it, and without connection with theratchet to the mainspring.

I claim- In combination with themainspring-barrel of a clock-movement, asecond spring-barrel, in connection with the mainspring-barrel by meansof a pawl and ratchet, and a cord or ribbon on said second barrel,substantially as described, so that drawing upon the said cordsimultaneously winds the spring in both barrels, the mainspring to drivethe clock-movement and the second to rewind the cord.

In testimony whereof I have signed my name to this specification beforetwo subscribing witnesses.
